So the big changes to Anti Vir yielded the following after a scanNo virus, but 4 warnings I've never got before. The question is should I worry?

The first one is some sort of file for Turbo tax.
The next two are sasasasasa quarantine logs.
The last is the antivir it self's install file!

No, it just means that they were excluded from scanning, because they are either password protected (an AV can't properly scan password protected files) or packed in a way (too many layers) that Avira couldn't unpack and scan it all. The warnings do not indicate malware or that something is wrong, just that the files/folders aren't in a scannable format. Avira couldn't scan them before the service pack update either, but maybe they have added more notifications about unscannable files now.
